Honeypot Guard is a powerful, privacy-focused anti-spam solution that protects your WordPress forms without annoying your visitors with CAPTCHAs. Using invisible detection techniques, it blocks spam bots while maintaining a seamless user experience.
<h4>Why Choose Honeypot Guard?</h4>
Unlike CAPTCHA-based solutions that frustrate users and hurt conversions (studies show CAPTCHAs reduce form submissions by 10-40%), Honeypot Guard provides superior spam protection with zero user friction.
<h4>How It Works</h4>
Honeypot Guard uses multiple layers of intelligent detection to catch spam automatically:
<ul>
<li>Invisible Honeypot Fields – Hidden fields that real users never see, but bots fill out automatically</li>
<li>Dynamic Field Rotation – Constantly changing field names make it harder for sophisticated bots to adapt</li>
<li>Timestamp Validation – Detects instant submissions (bots can’t read like humans)</li>
<li>Intelligent Gibberish Detection – Catches keyboard mashing and random text patterns</li>
<li>Advanced Heuristic Analysis – Pattern-based detection of common spam characteristics</li>
<li>Character Script Filtering – Optionally block submissions containing specific character scripts (Cyrillic, Chinese, etc.)</li>
<li>Cookie Verification – Proves JavaScript execution in a real browser environment</li>
</ul>
<h4>Key Features</h4>

<li>Granular Blacklisting – Block by email, domain, IP address, or keywords</li>
<li>Rate Limiting – Prevent spam floods with configurable submission limits</li>
<li>Detailed Spam Logs – View blocked submissions with one-click IP blocking</li>
<li>Multi-Language Admin – Available in 9 languages (English, German, Spanish, Italian, Lithuanian, Swedish, Polish, Estonian, Spanish-Mexico)</li>
<li>GDPR Compliant – No data sent to external services (unless you enable optional AI detection)</li>

<h3>Privacy Policy</h3>
Honeypot Guard collects and stores:
<ul>
<li>IP addresses of form submissions (for spam detection and blocking)</li>
<li>Form submission data flagged as spam (for review and pattern detection)</li>
<li>Timestamps of submissions (for rate limiting)</li>
</ul>
This data is stored in your WordPress database and is never sent to external services unless you enable optional AI-powered detection.
You can configure automatic deletion of spam logs in Settings > Honeypot Guard.
<h3>External Services</h3>
This plugin can optionally connect to external AI services for advanced gibberish detection. These services are disabled by default and must be explicitly enabled by the administrator.
<h4>OpenAI API (Optional)</h4>
When AI gibberish detection is enabled and configured with an OpenAI API key:
<ul>
<li>What it does: Analyzes suspicious form field content to detect nonsensical or spam text</li>
<li>Data sent: Only the specific text field being analyzed (not the entire form submission)</li>
<li>When sent: Only when a submission is flagged as potentially suspicious and AI detection is enabled</li>
<li>Service provider: OpenAI, L.L.C.</li>
<li>Terms of use: https://openai.com/policies/terms-of-use</li>
<li>Privacy policy: https://openai.com/policies/privacy-policy</li>

<li>Data sent: Only the specific text field being analyzed (not the entire form submission)</li>
<li>When sent: Only when a submission is flagged as potentially suspicious and AI detection is enabled</li>
<li>Service provider: Anthropic, PBC</li>
<li>Terms of use: https://www.anthropic.com/legal/consumer-terms</li>
<li>Privacy policy: https://www.anthropic.com/legal/privacy</li>
</ul>
